The task now is to build on this consensus and reach agreement, at Copenhagen, on a follow-up treaty to the Kyoto Protocol, which is due to expire in 2012. This new international agreement should translate the relevant scientific knowledge into a fair and practicable global strategy to combat global warming. So far, however, the lack of unanimity between the countries involved in the negotiating process has meant that there is no clear leitmotif pointing the way towards such an agreement.
